CAR-TRUCK BOLSTER.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed May 1,1907. Serial No. 371,254.

To all whom it may concern:

Be it known that I, Jenn- McE. Anns, a citizen of the United States, andresident of Dongan Hills, in the county of Richmond and State of NewYork, have 5 invented certain new and useful Improvements in Car- ITruck Bolsters, of which the following is a specification.

The. invention relates to improvements in pressed steel car-truckbolsters, and it consists in the novel features, arrangements andcombinations of parts hereinafter described and particularly pointed outin the claims.

The object of the invention is to produce a highly efficient bolstercapable of ready manufacture and possessiug great strength and rigidity.

In the preferred construction, the bolster of my invention comprises atop-plate, side-plates whose upper edge portions are flanged outwardlyand receive the rivets securing said top-plate, a channel-beam bottom 20or tension member whose flanges are between and riveted to said sideplates, inner braces of dished form within the end portions of thebolster and riveted to said side-plates, and a pressed steel innercenter-filler composed of two matched parts of dished form riveted 25together and to said side-plates, said bottom or tension member defininga bolster deepest at its middle portion and thence, at its bottom,curving upwardly toward its end portions which are horizontal to passthrough the truck side-frames and rest upon the usual springs, and 3said steel side-plates being extended below said bottom member along theadjacent curved and horizontal end portions of the latter at each sideof each end of the truck, whereby the bolster at the points wherepressed steel bolsters are most likely to break down is materiallystrengthened.

The invention will be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which:

Figure 1 is a top view of a bolster constructed in accordance with andembodying my invention; Fig. 2 is a side elevation, with onelongitudinal half in central vertical section, of the same; Fig. 3 is anenlarged top view of one end portion of the same; Fig. 4 is a verticallongitudinal section of the same on the dotted line 4-4 of Fig. 3, andFig. 5 is an end view, partly in central transverse section, of thebolster.

In the drawings, designates the top-plate; 11 the side plates whoseupper edges are flanged outwardly, as at 12, to receive the rivetssecuring said top-plate; 13 the bottom or tension member which is ofchannel shape andhas its edge flanges 14 between and riveted to the saidside-plates; 15 the inner dished shape end braces, and 16 thecenter-filler composed of the matched corresponding parts 17, 17 rivetedtogether and to said side-plates.

The top-plate 10 is a plain flat sheet steel plate of appropriate lengthand width and riveted to the flanges 12 of the side-plates 11, and saidtop-plate has secured upon it the center-bearing l8 and side-bearings19.

The side-plates 11 are plain fiat sheet steel plates flanged outwardlyat their upper edges, except at their end portions, and extendingdownwardly below the bottom member 13, as at 20, along those endportions of the latter where said bottom curves upwardly and thenceextends horizontally, as at 21, to form reduced end parts adapted topass through the truck side-frames and rest upon the usual springs, notshown.

The bottom-member 13 is a rolled channel whose edge flanges 14preferably extend upwardly and are riveted to the side-plates 11. Thechannel bottom member 13 is bowed downwardly at its middle portions, asshown, to define a bolster which is deepest at its central portions.

Upon the opposite sides of each end of the bolster are secured thewearing-plates 22, upon which are secured the column guides 23.

Within each end of the bolster are the box-like or dished braces 15,which are each in one integral plate pressed up to form a verticaltransverse member 24 having top, bottom and side flanges extending fromthe edges thereof and closely fitting between the sideplates 11 andagainst the inner surfaces presented by the bottom member 13, said sideflanges at their lower portions converging downwardly and inwardly toengage the facing sides of the channel flanges 14. The braces 15 are ofgreat strength and I provide two of them at each end of the bolster, thebraces being separated from each other and preferably having theirvertical members 24 facing each other and about in line with the columnguides 23. The braces 15 are secured by rivets 25 which pass through theside flanges thereof and also through the side-plates 11, wearing-plates22 and'column-guides 23. The wearing-plates 22 are further secured tothe side-plates 11 by rivets 26 whose inner heads are between the braces15 of each pair.

The two corresponding parts 17 of the center-filler 16 are each in oneintegral plate pressed up to form a vertical transverse member 27 havinga central vertical semi-circular recess 28 and top, bottom and side edgeflanges extending outwardly and closely fitting the inner walls at thecenter of the bolster, said side flanges at their lower portionsconverging downwardly and inwardly to engage the facing sides of thechannel flanges 14. The filler parts 17 have their vertical members 27in face to face contact and the recesses 28 therein match each other andform a circular recess or socket directly below and in line with theusual center opening in the center-bearing 18. The filler parts 17 areriveted together and to the side-plates.

The bolster as a whole is composed of but few parts easily manufacturedand securely riveted together and possesses a design and structureadapting it to meet all of the conditions which may be imposed upon itin service of the roughest kind. The vertical steel platesides of thebolster by extending vertically below the bottom member 13 to which theyare riveted very materially increase the resisting power of the bolsteras a whole and especially at those points at which steel plate bolstersare most likely to break down, and I recommend that the downwardlyextending portions 20 of said plate-sides commence at points inwardly ofthe vertical planes of the side-bearings and continue substantially orentirely to the outer ends of said bottom member. The extensions 20 ofthe plate-sides not only add to the efficiency of the bolster but may beused to house between them the upper portions of the bolster-supportingsprings.

What I claim as my invention and desire to secure by Letters-Patent, is:

1. A bolster comprising a top, steel plate sides and a bottom memberriveted thereto and defining a bolster deepest at its middle and havinghorizontal end portions, said plate sides being extended verticallybelow said bottom member along the adjacent upwardly extending andhorizontal end portions of the same; substantially as set forth.

3. A bolster comprising a top-plate, steel plate sides whose upper edgeportions are flanged outwardly and riveted to said top-plate, and abottom member between and rivetedto said sides and defining a bolsterdeepest at its middle and having horizontal end portions, said platesides being extended vertically below said bottom member along theadjacent upwardly extending and horizontal end portions of the samesubstantially as set forth.
